As for buying a basket pre-made, I believe you are out of luck.
To do it right you will need to create it yourself. Go to trader Joe’s, sprouts or even a Mother’s market and get some cheese. Where to go depends on wheer in the Inland Empire you are. If close to Claremont you also may want to try Wolfes on Foothill.
Get about 3-5 differing types, ask questions at the locations and add some funky type of bread or crackers.
Making it yourself will be more fun and will also allow you to try some of them a well.
